Recent Landslide Hazard Assessments

Updated January 13, 2021

2020 Post-Wildfire Watershed Emergency Response

CAL FIRE and the California Geological Survey deployed Watershed Emergency Response Teams (WERTs) to recent burns located within state responsibility areas. Requests for WERT report information should be directed to CAL FIRE. (CAL FIRE by default provides WERT hazards evaluation reports and maps to affected communities, flood control managers, and emergency managers.) To learn how the CGS works with CAL FIRE and others to analyze landslide potential on newly burned landscapes, visit the CalConservation blog: Notes from the Field.
